Update items.

Currently there is no update for `channels`, `job` and `permissions`.
Add them.

The issue mentions adding updates for 'channels', 'job', and 'permissions' but does not specify what to update or where. Look at the repository's codebase to understand the existing structure for these items, likely in modules or configuration files. Check for any related tests or documentation to infer the expected behavior. Determine what 'update' means in this context—whether it's adding new fields, methods, or functionality.
